' This invention relates' to a vise designed morev especially for use inthe assemblyof leaf springs such as used on automobiles and..

other vehicles, one of thev objects being to 5 j rovide` afdevice whichA'can be compactly stored, easily assembled for use and .can be employedas an ordinary vise for gripping pipes, angularstructures' and specialwork,

it being possible to changethe jawsquickly.v

AnotherY object 'is` to provide a means whereby removablejsupplementaljaws can interlock with their Vholders and thus be heldagainstaccidentaldisplacement. Vith "the foregoing and other objects in 5 View whichwillr appear as thev description Aproceeds,`the invention resides in thecombination and arrangement of partsv and Tin the details ofconstruction hereinafterr described and claimed,` itr being Aunderstoodo that changes in the preciseembodiment of the invention" hereindisclosed may be Vmade within the scope of what is claimedwithoutV 0 jFigure 2 is a section online 2 2, Figure l, supplemental jaws beingshown connected to the main jaws.,V f 1 Figure 3 is a section on line3-A-35'Figure 2. -Figure 4 is a rear elevation of the removgableSuppkgmental jaw shown inFigure 2.

Referring to the iigures by characters of reference l'designates abox-like base the flat top of which is provided with an elongatedcentral opening 2 SideV ianges 3 extend from the top of the base andconstitute conywall of the basee'Xt-ends between this collar and head 7'so thatthe'sclrew 'is thus held `ing 2 'is a stationaryjaw 12 the.middlefportween the" opposite face of the; jgw and :base l. l Y.,

. A-movabl'e jaw issupportedfdetachably by the base `and hasbeenindicated atf16; This movable jaw is formed withal bottom 17 i'adapted t0 rest upon bas 1n This ,boaom'@ extends beyond the 'side'flanges '3 andihas depending inturned flanges 18 'adapted to ystraddleflanges 3 and thus holdjaw 16 assemy bled withithebase.` Bylmo'ving thejaw 16 to a point betweenthe cut awayipjortionsli," j it becomespossibleto lift the jaw from the base; 5'" I" Ribs `19 are formed ontheactiveface-oiijaw V16 and extend from the'top thereot topoints.

portionfof the jaw is cut away as indicated is insertible transverselyinto the slot and its height is less than the height of the slot, thusthe nut and the block 22 can have sliding bore 23 and screwed throughthe nut 25`until one end of the feed screw becomes seated in the otherendof the base.V Sleeve l1 is then adjusted against the inner side ofthe base and secured to the screw so that it, in cooperation with head 7will hold the screw against :longitudinal movement.

The spring or kother work to which the device is adapted to be placedbetween the Vjaws 12 and 16 and where it will be held against lateraldisplacement by the ribs 14 and 19. By rotating the screw the jaw 16will be shifted relative to jaw 12 thereby placing the spring under thedesired'coinpression or releasing it as desired. j

' This device can be used as an ordinary vise by combining supplementaljaws with the `main jaws. In Figures 3, 4, and 5, a movable supplementaljaw has been shown. This jaw 26 is formed in its backxface with recesses27 one or more of which are adapted to receive the ribs 19 while at thesame time the jaw will thrust firmly against the main jaw 16. A lug ,23is formed on the back of the supplemental jaw 26 and has a screwthreaded stud 29 projecting therefrom which is adapted toextend througha clamp 30.

After the supplemental jaw has been applied'to the main jaw at whichltime it extends both under andpover the ribs 19, as

shown in Figure 2, the -clamp, 30 is placed between the ribs 21 and onstud 29. Viing nut 31 or the like islthen screwed onto the stud 29 so asto bind the clamp 30 upon the jaw 16 and thereby hold the supplementaljaw securelyvin position. VSmall centering wings'32 can be extendeddownwardly from jaw 26 to facilitate its assembly with the main jaw. Y

. The other supplemental jaw 33 is adapted to be assembledv with themain aw 12 and has recesses 34V in 'its back face one or more of whichare adapted to receive the ribs 14. Jaw 33 not only bears against theribs 14 and jaw 12 but also laps the topof the jaw 12 and has a flange35 which extends under said jaw. Lug 36 is formed integral ywith jaw 33and has a screw threaded lstud 37 for engagement by a clamp 38; Thisclamp is adaptedto bear against the jaw 12 between webs 15 and by meansof a nut 39 enthe vise thus used for ygripping round obj jects such aspipes. One of the supplemental jaws -thus constructed has been shown inFigure 9. f

Supplemental jaws of other forms for yholding' special work can be usedwithL this For example,y andas shown in e structure. l Figure 8, thesupplemental jawv 42v can'be made with'an angular recess 43 in its`workingface, this recess beinglined with leather or other softmaterialindicated at 44. A4

jaw of this construction can be used for hold- 'ing pistons and thelike.

Vhen the device herein described lis not in use or is to be stored ortransported, the Ysliding jaw can be Ydetached readily from the ybaseand the screw can'be removed as will be obvious. By pivotally connectingthe crank to the screw4 it can be swung to any vdesired angle tofacilitate packing. Openj `ings 45 can be provided in the base toreceive screws or the like used for fastening it to a bench. l Y

What is claimed is: Y Y l j 1., A vise including a slotted base, a' feedscrew therein, fixed and movable jaws on the base, an operativeconnection between c the screw andl movable jaw, arib on one face Vofeachv jaw, supplemental jaws bearing .against and adapted to receive theribs, said ribs constituting means Vfor holding the Vsupplemental awsagainst lateral displacement, and means carried Vby the supplementaljaws for clamping them to the main jaws. y

2. -A viseincluding a slotted base, a feed screw therein, fixed andmovable jaws on the base, an operative connectiony between the screw andmovable jaw, a rib on one Vvface of each jaw, supplemental jaws bearingagainstand adapted to receive the ribs,

said ribs constituting means for holding the Asupplemental jaws againstlateral displacement, means carried bythe supplemental jaws for clampingthem to the main jaws, andmeans on the supplemental jaws for extendingover and under the ribs on the main jaws to` interlock therewith.

, In testimony that I claim the foregoing as my own, T have heretoaffixed my signature. l
